Time performance
※
Accuracy of the mechanical watch is different from the daily rate of the quartz watch and the accuracy will change
maximum of several ten seconds during rewinding the spring, then the accuracy of the half winding condition will
be different from that of full winding condition.
<Time performance measurement condition>

Measure within lapse of 10
～
60 minutes from full winding.
Posture difference
Measure accuracy in 4 different postures shown on the
right picture within lapse of 10 ~ 60 minutes from full winding.
